            layout.delegate = self
            layout.sectionInset = UIEdgeInsets(top: 16, left: 16, bottom: 16, right: 16)
            layout.minimumLineSpacing = 8.0
            layout.minimumInteritemSpacing = 8.0
            layout.headerHeight = 50.0
            collectionView.collectionViewLayout = layout

extension ViewController: WaterfallLayoutDelegate {
    func collectionViewLayout(for section: Int) -> WaterfallLayout.Layout {
        switch section {
        case 0: return .flow(column: 1) // single column flow layout
        case 1: return .waterfall(column: 3) // three waterfall layout
        default: return .flow(column: 2)
